Tesco is facing Britain's largest ever equal pay claim and a possible compensation bill of up to 4 billion pounds (C$7 billion), according to a law firm which has begun legal proceedings. It comes as a campaign for equal pay grows in the U.K.

The Federal Court has overturned a health and safety tribunal’s findings that Air Canada flight crew members didn’t have a legitimate reason to refuse work over strange smells on aircraft caused by leaking oil and other fluids.

On June 23, 2011, an Air Canada plane was scheduled to fly from Edmonton to Vancouver, and then from Vancouver to Toronto. The service director on the plane for both flights was Francisco Diaz Delgado and he was accompanied by two flight attendants on each flight.

Shortly after takeoff of the Edmonton to Vancouver flight, Diaz Delgado noticed a smell that reminded him of “blue cheese,” “dirty socks,” and a “smelly gym bag.”
